Hello all,
I have LCD 2004 (shorturl.at/yEKU4) and Anet v1.7 board (shorturl.at/qrvBV) but I have no idea, how to make program for working LCD with buttons. I2C scanner founded nothing.
I hadn't any problem to connect stepper motors, but with LCD I have a prob. When I uploaded Marlin fw (GitHub - MarlinFirmware/Marlin: Marlin is an optimized firmware for RepRap 3D printers based on the Arduino platform. | Many commercial 3D printers come with Marlin installed. Check with your vendor if you need source code for your specific machine.), LCD works fine. So I don't know how to make a program.
Have you some example code please? You will be great.
Thank you very much for your help.
